Offshore wind prices reach record breaking levels

The latest UK auction for clean energy (September 2017) were won with bids from three offshore wind projects based in UK waters with prices ranging from £57.50 per MWh  in 2022/20023 to £75.75 per MWh in 2021/2022 for a total of 3.2 GW  of capacity.  This raises the question, is this  just the lowest hanging fruit or will we see prices firming around this range and even falling as turbine size increases towards 15 MW,  what are the impacts for the nascent wave and tidal energy industries and how should they respond ?
